Bivariate Data

Front

What is bivariate data?

Back

Bivariate data involves two variables and is used to determine the relationship between them.

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for two variables for a set of data.

Front

What does a negative correlation indicate in a scatterplot?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What is an outlier in a scatterplot?

Back

An outlier is a data point that differs significantly from other observations, often lying outside the overall pattern.

Front

How can you identify a positive correlation in a scatterplot?

Back

A positive correlation is identified when the data points trend upwards from left to right.

Front

What does it mean if a scatterplot shows no correlation?

Back

No correlation means there is no discernible relationship between the two variables; the points are scattered randomly.

Front

What is the purpose of analyzing bivariate data?

Back

The purpose is to understand the relationship between two variables and make predictions based on that relationship.

Front

What is a linear association in bivariate data?

Back

A linear association means that the relationship between the two variables can be represented by a straight line.

Front

What does it mean if a scatterplot is described as 'not linear'?

Back

It means the relationship between the variables does not follow a straight line, indicating a more complex association.

How can temperature affect the number of hikers in a scatterplot?

Back

Temperature may show a non-linear association with the number of hikers, where certain temperatures attract more or fewer hikers.
